Scaphoid fractures are the most common carpal fracture, representing 70% of carpal bone fractures. The diagnostic accuracy of physical examination findings and emergency medicine (EM) imaging studies for scaphoid fracture has not been previously described in the EM literature. Plain x-rays are insufficient to rule out scaphoid fractures in a patient with a suggestive mechanism and radial-sided tenderness on physical examination. This study was a meta-analysis of historical features, physical examination findings, and imaging studies for scaphoid fractures not visualized on plain x-ray in adult emergency department (ED) patients, specifically to address which types of imaging tests should be recommended in patients with persistent concern for acute fracture after ED discharge. ⋯ Except for the absence of snuffbox tenderness, which can significantly reduce the probability of scaphoid fracture, history and physical examination alone are inadequate to rule in or rule out scaphoid fracture. MRI is the most accurate imaging test to diagnose scaphoid fractures in ED patients with no evidence of fracture on initial x-rays. If MRI is unavailable, CT is adequate to rule in scaphoid fractures, but inadequate for ruling out scaphoid fractures.

Thrombin generation and fibrin clot formation under hypothermic conditions: An in vitro evaluation of tissue factor initiated whole blood coagulation.
Despite trauma-induced hypothermic coagulopathy being familiar in the clinical setting, empirical experimentation concerning this phenomenon is lacking. In this study, we investigated the effects of hypothermia on thrombin generation, clot formation, and global hemostatic functions in an in vitro environment using a whole blood model and thromboelastography, which can recapitulate hypothermia. ⋯ Induced hypothermic conditions directly affect the rate of thrombin generation and clot formation, whereas global clot stability remains intact.

Psoas:lumbar vertebra index: central sarcopenia independently predicts morbidity in elderly trauma patients.
Central sarcopenia as a surrogate for frailty has recently been studied as a predictor of outcome in elderly medical patients, but less is known about how this metric relates to outcomes after trauma. We hypothesized that psoas:lumbar vertebral index (PLVI), a measure of central sarcopenia, is associated with increased morbidity and mortality in elderly trauma patients. ⋯ Psoas:lumbar vertebral index is independently and negatively associated with posttraumatic morbidity but not mortality in elderly, severely injured trauma patients. PLVI can be calculated quickly and easily and may help identify patients at increased risk of complications.

Fast Track by physician assistants shortens waiting and turnaround times of trauma patients in an emergency department.
We sought to determine whether the introduction of a separate patient flow comprising patients with simple, non-complex health issues [Fast Track (FT)] in a Dutch emergency department setting (ED), without the introduction of additional staff, and treated by a physician assistant, would have favourable effects on waiting and turnaround times without deleterious effects for patients with a higher urgency. ⋯ The introduction of FT performed by a physician assistant resulted in a significant drop in waiting time and length of stay in a Dutch ED setting. This reduction was realised without the allocation of additional staff and even reduced waiting and turnaround times for the patients with a high urgency.

The objective was to determine if use of ultrasound (US) by emergency physicians (EPs) to localize spinal landmarks improves the performance of lumbar puncture (LP). ⋯ These data do not suggest any advantage to the routine use of US localization for LP insertion, although further study may be warranted to look for benefit in the difficult to palpate or obese patient subgroups.
